I apologize if this is a question with an obvious answer. My Perl is weak. I am trying to upgrade otrs from 2.4.7 to .3.0.1. I downloaded otrs-3.0.1-01.noarch.rpm and updated the existing version (rpm -Uvh). Then when I try to start httpd, I get this: [Mon Apr 23 15:27:19 2012] [error] Insecure dependency in require while running with -T switch at /opt/otrs//Kernel/Config/Defaults.pm line 37.\n at /opt/otrs//Kernel/Config/Defaults.pm line 37\n\tKernel::Config::Defaults::BEGIN() called at /opt/otrs//Kernel/Config/Defaults.pm line 37\n\teval {...} called at /opt/otrs//Kernel/Config/Defaults.pm line 37\n\trequire Kernel/Config/Defaults.pm called at /opt/otrs//Kernel/Config.pm line 161\n\tKernel::Config::BEGIN() called at /opt/otrs//Kernel/Config/Defaults.pm line 37\n\teval {...} called at /opt/otrs//Kernel/Config/Defaults.pm line 37\n\trequire Kernel/Config.pm called at /opt/otrs/scripts/apache2-perl-startup.pl line 67\n\tmain::BEGIN() called at /opt/otrs//Kernel/Config/Defaults.pm line 37\n\teval {...} called at /opt/otrs//Kernel/Config/Defaults.pm line 37\n\trequire /opt/otrs/scripts/apache2-perl-startup.pl called at (eval 56) line 1\n\teval 'require qCompilation failed in require at /opt/otrs//Kernel/Config.pm line 161.\n at /opt/otrs//Kernel/Config.pm line 161\n\tKernel::Config::BEGIN() called at /opt/otrs//Kernel/Config/Defaults.pm line 161\n\teval {...} called at /opt/otrs//Kernel/Config/Defaults.pm line 161\n\trequire Kernel/Config.pm called at /opt/otrs/scripts/apache2-perl-startup.pl line 67\n\tmain::BEGIN() called at /opt/otrs//Kernel/Config/Defaults.pm line 161\n\teval {...} called at /opt/otrs//Kernel/Config/Defaults.pm line 161\n\trequire /opt/otrs/scripts/apache2-perl-startup.pl called at (eval 56) line 1\n\teval 'require qCompilation failed in require at /opt/otrs/scripts/apache2-perl-startup.pl line 67.\n at /opt/otrs/scripts/apache2-perl-startup.pl line 67\n\tmain::BEGIN() called at /opt/otrs//Kernel/Config.pm line 67\n\teval {...} called at /opt/otrs//Kernel/Config.pm line 67\n\trequire /opt/otrs/scripts/apache2-perl-startup.pl called at (eval 56) line 1\n\teval 'require qCompilation failed in require at (eval 56) line 1.\n at (eval 56) line 1\n\teval 'require q [Mon Apr 23 15:27:19 2012] [error] Can't load Perl file: /opt/otrs/scripts/apache2-perl-startup.pl for server it2.hq.marquee.net:0, exiting... So I understand -T is tainted mode for Perl. It is disabled in my httpd.conf, so maybe it is triggered at somewhere else I am not aware of? Or something else is causing this?
